  • Due to geographical restrictions, Tibetan dwellings mostly adopts traditional stone-wood structure system, which has no seismic design and is easy to be severely damaged by earthquake disasters. In order to understand the weak links of Tibetan-style stone-wood structure dwellings under earthquake action, a typical stone-wood structure dwelling in the suburbs of Lhasa was selected as the research object, and its displacement and acceleration response under three groups of frequent earthquakes were analyzed through ANSYS modeling. As well as the acceleration response, displacement response and stress cloud diagram under the action of the El-Centro rare earthquake wave, the inter-storey drift angle and acceleration magnification factor were calculated; in addition, combined with the distribution of structural shear stress, it was found that under seismic action, the main weak points were the parapet wall, the second-story column joints, the walls near the door and window openings, and the corners; finally, some suggestions for strengthening and improving this type of structure were given based on the analysis results.
